DMA or Dynamic Mechanical Analysis is a powerful analytical technique for investigating the temperature and frequency-dependent behavior of polymeric materials. 

DMA can be used to determine fundamental transition temperatures, such as glass transition, and how that value changes with material formulation and conditioning. The mechanical response of different materials being considered for an application can be compared over the temperature range anticipated in service. More advanced applications for the DMA include stress-relaxation behavior and creep testing.

DMA measures the modulus (stiffness) and damping (energy dissipation) of materials as they are deformed under periodic stress. It can be used to assess the effects of temperature on a material, and characterize its physical properties.. 

Effective for polymers, plastics, rubber

For plastics, rubbers, and other polymeric materials, which are viscoelastic and have mechanical properties that are subject to time, frequency and temperature, DMA is an effective method. Element experts use DMA to measure:

  • Modulus
  • Creep and Stress Relaxation 
  • Film/Tension Behavior
  • Damping 
  • Glass Transition and Softening Temperature 
  • Cure Behavior
  • Rectangular Torsion
  • Shear Modules (G'G" TAN)
Plan for long-term service life for your plastics and polymers

To fully understand properties and predict their performance over the lifetime of specific applications, engineers sometimes use short-term test information to project long-term high-temperature performance. DMA is a better way to evaluate and predict long term service life, and as such provides a more realistic indication of properties.
